2. Loosen the two nuts which secure the top of the chassis with an 11/32” socket.
3. Carefully lift up and remove the chassis assembly from the backbox and store in a safe, clean place. Avoid static discharge which
may damage static sensitive components on the board.

page 24.
2. Install center top fastener in the wall with the screw head protruding.

4. Mark and drill the left and right upper and lower mounting holes.
Note: Outer holes (closest to sidewall) are used for 16” O.C. stud mounting.

6. Carefully reinstall the chassis assembly and dress panel by reversing the steps above. Use appropriate precautions to prevent
damage to components due to static discharge. When reinstalling the chassis assembly, be sure that all four (4) tabs are seated
